PHITE & PAPER COMPANY, or-roa'r Horton, MICHIGAN" BE'A'I'ING-ENGIiIE Buchanan Application filed April 12, This invention relates to improvements in devices for indicatingthe operation of beating or grinding elements in machlnes n whichthe material being beatenor ground 5 is fed between two of such elements which may be relatively adjusted while operating". It is particularly designed for use-with machines of the pulp beater type commonly employed in the manufacture of paper stock.

In the preparation of raw material for the manufacture of paper a beater is used; and the raising or lowering of the beater roll' on the raw material affects the character of the paper very decidedly. It is, therefore, of .15 great importance that the operator of the beating engine has at all times some means for determining the pressure of the beater roll on the stock; in-orderthat he may regulate the machine to vary the roll pressure in 0' accordance with the desired characteristics of the finished product.

Accordingly, the main object of the present invention is to provide an: attachment for beating engines which will not only indicate the pressure of the beating roll on the stock and bed plate; but which will also make a permanent record of each run of the machine, indicating whether or not the operator had maintained the beating roll at the proper adjustment during the run. Another object of the invention is to provide a pressure indicator and recorder with removable record sheets, each of which has a standard pressure line to indicate to the operator the pressure desired during'any particular run and to indicate, after a run, any departure from the desired standard pressure. A further obj ect' of the invention is to prowhich is automatically operated by the weight of the beater roll alone and which does not in any way interfere with the usual setting apparent as the detailed description thereof proceeds.

In the drawing: r

Fig. 1 is a perspective view of onefonn of my invention applied to a beating machine;

Fig. 2 is a side elevation, with parts broken vide an operating means for the recorder Ito and carried by a lever 192a. -Serial No. 269,479. I

Fig. 5 is a horizontal section on the line 55 of Fig. 4;

of the deviceshown Fig. 6 is a vertical section on the line I of Fig. 4;; and Y Fig. 7 is a horizontal section on the line 77 of 2. ,L In the drawings, the beater roll 1, provided with the'usual beater knit yes 2, is illustrated e5 as mounted to rotate in the beater tub 3 on a shaftl which is rotatablymounted in bear- 'ing 5 carried by the lighter bars 6.

As is usual in; machines of this type one (end of each lighter bar 6 is supported by a knife edge fulcrum17, formed or otherwise fixed in a supporting standard 8 suitably se-' cured by bolts 9 to a supporting base or fioor. Four of these standards support the operating mechanism of the beating engine, and are rigidly secured to each other by webs 10 or other suitable framework. Quick-lift bars 11 are secured to the ends of the lighter bars resting onfulcrums 7 to raise the lighter bars, and the beater; roll' carried thereby, whenever 1t becomes necessary or desirable to raise them.

The other end of the front lighter bar 6 is supported by an adjusting screw 12 which extends upwardly through the top of one of the standards 8 ,into screw threaded engage ment with a worm gear 13 mounted to rotate abouta vertical axis on a bracket 14'secured The'lever 15 has one end thereof provided with a-notch 16 adapted to receive a'knifeedged fulcrum plate 17 bolted to the upper end-of an angleiron 18fiXed to the front v web 10. The lever 15 is shaped as a channel iron and hasits side flanges straddled over the top of the adjacentstandard' 8 while the free end of the connecting web par-t'thereof is screw threaded to receive anacljustingv screw 19, a screw threaded reinforcin plate 20 being welded to said part to prom e sufficient bearing for the screw threads of the screw 19.

The screw 19 swivels at its lower end in a circular disk 21, having its lower face 22 made slightly spherical to rest upon an elastic diaphragm 23 forming part of a device for transmitting the pressure of face 22 to the pressure indicating and recording instrument, to be described hereinafter.

A shaft 24 extends from the front to the rear of the'machine and is mounted in bearings 25 and 26 fixed to the bracket 14 and a rear standard, respectively; Near its front end, the shaft 24 has a worm 27 formed or suitably secured thereto; and this worm 27 meshes with theworm gear 13 to rotate the latter and thereby raise or lower the screw .12, and the end of lighter bar 6 carried thereby, relative to the fulcrum bar 15.

The shaft 24, at its rear end, has fixed thereto, or formed thereon, a worm 28 meshing with a worm gear 29 journaled on top of a rear standard 8, and in screw threaded connection with another main beater roll adjusting screw 30 which is fixed at its lower end to one end of the rear lighter bar 6.

A handwheel 31 fixed on one end of shaft 24 rotates the shaft 24, and through worms 27 and 28 and worm gears 13 and 29, raises or lowers the beater roll adjusting screws 12 and 29 simultaneously to raise or lower the lighter bars 6 and the beater roll journaled thereon.

The channel iron 15 supporting the worm bearing bracket 14 is supported at one end by the knife edge 17 and at its other by the adjusting screw 19 which bears directly on the elastic diaphragm 23 of the pressure transmitting device. The screw 19 may be adjusted to raise the channel iron 15 slightly from the top of the adjacent standard 8; and, since this channel iron 15 supports the screw 12, this adjustment of screw 19 throws the weight of one end of the front lighter bar onto the diaphragm 23 'to transmit the weight of the beater roll thereto for the purpose of having the pressure of the roll on the stock indicated and recorded.

The pressure gage 32 is of any ordinary time-controlled pressure actuated type, adapted to receive detachably a record card 33 and to rotate this card by the usual clockwork under an indicating and marking instrument 34. Preferably, each card is provided with a standard pressure line 35 to indicate the pressure of the beater roll desired in a particular run, and to serve, in conjunction with said marker, as a standard to indicate to the engine operator how to adjust the beater roll to obtain-the desired results.

At the end of any run the markings recorded on the card by marker 34 show clearly all irregularities in the adjustment of the beater roll.

The pressure indicator 32 may-be placed adjacent the beating machines as shown in Fig. 1; or may be mounted at any desired distance therefrom and wherever found convenient.

To operate the recorder 32, a pressure transmitter 36 is interposed" between the beating engine and the recorder. As shown in Figs. 1, 4, 5 and 6, this transmitter comprises a bracket 37 bolted to the standards 8 immediately below the channel lever 15.

The horizontal branch 38 of bracket 37 is provided with a circular aperture 39' over which is stretched an elastic diaphragm 40; and a plate 41 having an aperture 42 of the same size as aperture 39 overlies diaphragm 40, with the said apertures registering, and is securely bolted to branch 38 to clamp the diaphragm 40 thereto.

The diaphragm 23 is stretched over plate- 41, and is securely clamped thereto by the annular plate 43, which also has a central circular aperture 44, registering with apertures 39 and 40 in branch 38 and plate 41 respectively.

The annular plate 43 is clamped to the diaphragm 22 and plate 41 by means of bolts 44' passing through registering apertures in branch 38 plate 41, plate 43, diaphragms 22 and 40, and oppositely disposed yoke brackets 45 and 46, which extend across the branch 38 to carry contact devices for the diaphragms 22 and 41. j

The upper diaphragm 22 supports the disk 21 at the lower end of adjusting screw 19; while the lower diaphragm 40 rests upon the slightly spherical face 47 of a disk 48 which is fixed to the end of an adjusting screw 49 screw threaded into the yoke 46.

The space between the diaphragms 22 and 40 is filled with any suitable liquid, and communicates with the operating chamber or chambers in recorder 32 through the piping 50'connecting said recorder 32 to a passageway 51 formed in the central plate 41. Any desired number of passageways, similar to passageway '51, may be provided in plate 41 to communicate with a corresponding number of recorders located wherever desired. One of these additional passageways 52 is shown in Fig. 5 and is provided with a plug 53 which may be removed to receive piping for operating another recorder if desired. I

The disk 48 may be adjusted by screw 49 to obtain any desired initial setting of the recorder marker 34. When this setting is obtained the wheel 31 may be rotated to operate the screw 12 through worm 27 and gear 13' to transfer the weight of one end of the front lighter bar 6 from the fulcrum 7 onto the lever 15, and, thence through adjusting screw 19 onto the elastic diaphragm 22.

It will. be obvious that, as the stock passes between the beater roll and the bed plate,

the pressure of the roll on diaphragm will vary in accordance with variations in the density of the stock; and these variations will be indicated and recorded on the recorder 32, which Will indicate to the operator whether the roll is or is not properly adjusted to conform as closely as practicable or desirable to the pressure standard required by line 35.

The indications of the recorder also serve to indicate whether the raw material passing under the beater roller has been properly prepared and is free from undigested chunks ofwood or other matter which might injure the machine or quality of the product.

Having thus described my invention, what I claim is:

1. The combination with beating or grinding elements, of means for relatively adjusting said elements, a pressure indicator, and fluid pressure actuated means connected to said adjusting means to cause said indicator to indicate relative movements of said elements.

2. In combination with a beating engine including a pressure roll and a bed plate, means for indicating and recording the pressure which the beating roll exerts upon said bed plate.

3. In a beating engine comprising a heater roll having adjusting means, an indicating and recording device automatically operated by the weight of the beating roll alone, inde-' pendently of the beating roll adjusting means.

In testimony whereof I aflix my signature.

EDWARD A. HAYNES.
